Harry Hill McAlister (July 15, 1875 – October 30, 1959) was an American lawyer and politician who served as the 37th governor of Tennessee from 1933 to 1937.

Inaugurated as governor at the height of the Great Depression, McAlister enacted massive spending cuts in an attempt to stabilize state finances.

As a state senator, he sought stricter enforcement of laws regarding education and child labor, and advocated better food and drug inspections.

During the 1920s, he consistently warned that the state faced an impending financial crisis, and assailed Governor Austin Peay's reforms.

Peay had radically transformed the state government, and had angered numerous members of his own party in the process, among them political bosses E. H. Crump of Memphis and Hilary Howse of Nashville.

[3] In 1928, McAlister again sought the nomination, this time against incumbent Henry Horton, who had become governor following Peay's death the previous year.

A few days after Horton's victory in the general election, numerous banks controlled by Lea's business associate, Rogers Caldwell, failed, wiping out over $6 million in state deposits.

While the motion calling for Horton's impeachment failed in the state House, both Caldwell and Lea were eventually convicted on charges of bank fraud.

Although Horton had survived impeachment, he did not seek further reelection, and McAlister's main competitors were Pope and former governor Malcolm R. Patterson.

Crump's allies in the state house defeated the tax, and he broke off support for McAlister, calling him "our sorriest governor.

[9] McAlister was descended (via his mother) from two former Tennessee governors, Willie Blount (1768–1835), his great-great-grandfather, and Aaron V. Brown (1795–1859), his great-grandfather.
